Title:
SYSTEMS AND METHODS FOR APPLYING FLUX TO A QUANTUM-COHERENT SUPERCONDUCTING CIRCUIT
Document Type and Number:
WIPO Patent Application WO/2014/028302
Kind Code:
A3
Abstract:
Systems and methods are provided for applying flux to a quantum-coherent superconducting circuit. In one example, a system includes a long-Josephson junction (LJJ), an inductive loop coupled to the LJJ and inductively coupled to the quantum-coherent superconducting circuit, and a single flux quantum (SFQ) controller configured to apply a SFQ pulse to a first end of the LJJ that propagates the SFQ pulse to a second end of the LJJ, while also applying a flux quantum to the inductive loop resulting in a first value of control flux being applied to the quantum-coherent superconducting circuit.
